`declaration_naming` not respecting type factory

[KurtWagner]

For example,

error Constant declaration should be snake_case [game-src/utils.zig:18:7] declaration_naming

 18 | const MinimumNewLinesType = std.math.IntFittingRange(0, 200);
    |       ^^^^^^^^^^^^^^^^^^^

Related to #83

Another problem is around evaluating results of a switch expression in a declaration. e.g., the following should be classified as a type and have type naming requirements enforced.

const MyInt = switch(size) {
   .small => u32,
   .large => u64,
};
